VEHlCLE-SEAT.

SPECIFICATION forming part of Letters Patent No. 288,610, dated November 20, 1883,

. Application filed March 24,1883. (No model.)

T aZZ whom it. may concern.-

.Be it known that I, J OHN W. ANDERSON, a citizen of the United States, residing at South Bend, in the county of St. Joseph and State of Indiana, have invented new and useful Improvements in the Construction of Vehicle- Seats, of which the following is a specification.

My invention relates to improvements in vehicle-seats when the backs are composed of thin layers of wood cemented together; and the objects of my improvements are, first, without apparently increasing the thickness of the seatback, to provide an increased bearing-surface on the bottom edge of same, so that it will rest firmly on the bottom board or frame; second, to afford sufficient thickness at the bottom of the back to allow screws to be used in the edge to hold the back down on the bottom frame; and, third, to protect the upper edge in a neat and substantial manner. I attain these objects by the construction shown in the accompanying drawings, in which Flgure I is a perspective view of a portion of a wagon seat embodying my invention, and Fig. 2 is a sectional view of same.

Similar letters indicate like parts in both figures.

The seat-back A is composed of several thicknesses of thin wood cemented together. 0 is a tapering core, preferably a wedgeshaped strip placed between the laminae of the seat-back at the bottom edge for the purpose of increasing the thickness, so that it can be seated firmly on the bottom frame, B. The taper core 0 enables me to use screws to secure the back A to the top of the bottom frame, B, which would be impracticable if only thin veneers were used in the construction of; the back.

My improved seat-back is seated on top of the bottom frame and held in its place by any suitable means, but preferably by screws passing through the bottom frame and up into the bottom edge of the back. This construction leaves the bottom frame, B, of full thickness to the edge of the molding, which is stronger and more symmetricalin shape than where a groove or rabbet is cut in the bottom to re ceive the lower edge of the back, as is necessary with all laminated seat-backs used prior to my invention. The swell produced by the core 0 comes on theinside of the seat, leaving the outside of the back A of uniform flare, thus preserving the lightness and grace of appearance. I use the tapering core 0 in both square and round corner seats, the forms or molds being shaped to conform to the swell produced by the insertion of thewedge-shape filling.

To protect the upper edge of my improved seat-back, I use an angle-iron, D, bent to conform to the curves of the edge of the back, and held in place by nails, screws, or rivets. One flange of the angle-iron D lies on the inside of the back, and the other flange covers the upper edge. The upper flange of the angle-iron D is flush with the outside of the back A, which allows the wood to be painted and finished quite up to the top edge. 7c

I am aware that it has been common to construct various parts of carriages ,of veneers cemented together, and laminated seat-backs held to the base-frame by a groove or rabbet are in use, so I make no broad claimto a seatback constructed by gluing together layers of veneers; but

What I claim as my invention, and desire to secure by Letters Patent, is

1. A wagon-seat back, A, composed of thin 8( layers of wood, having a tapering core, 0, inserted between the layers, in combination with the bottom frame, B, constructed substantially as and for the purposes set forth.

2. In a vehicle-seat, the wedge-shape strip 8 Cand laminated back A, united and combined substantially as described.

3. In combination with the laminated seatback A, having a tapering strip inserted be tweenthe layers, the angle-iron D, constructed and applied substantially as shown and described.
